== SYNOPSIS
require ‘icmpping’
result = ICMPPing.ping hostname [, timeout(millisecs) [, packetsize(<1024)]]
== Return Value
-1 : Any Socket Error
-2 : Timeout
-3 : Not root
=0: round trip time (in milliseconds)
== Notes
Only Linux now supported
You must be root
Miliseconds now work correctly
Only a class now

I have installed it but with this script I have this error:
Error
pin.rb:5: parse error
t = Net::PingTCP.new(192.168.1.1
Script
require ‘net/pingsimple’
check with udp or tcp ping
t = Net::PingTCP.new(192.168.1.1)
#u = Net::PingUDP.new(host)
#e = Net::PingExternal.new(host)
if t.ping
puts “Host is alive”
unless t.warning.nil?
puts "Warning encountered: " + t.warning
end
else
puts "Couldn’t connect to host: " + t.exception
end
Please can you say me how to write a scrip correct that to do a ping to
192.168.1.1 ???
Thank you

That’s not a string, use “192.168.1.1”

Actually, this is good. It means that you are actually making ICMP
(ping) requests.

FAQ

===
“Why don’t you return exceptions if a connection fails?” - Because ping is
only meant to return one of two things - success or failure. It’s very
simple. If you want to find out why the ping failed, you can check the
‘exception’ attribute.
“I know the host is alive, but a TCP or UDP ping tells me otherwise. What
gives?” - It’s possible that the echo port has been disabled on the remote
host for security reasons. Your best best is to specify a different port
or to use PingExternal instead.

Ok script is ok if I use Net::PingExternal.new.
When ip address that I put is live script is ok, but when I put into
script a ip address wrong I don’t know how to set a timeout.
I put timeout:
pe = Net::PingExternal.new(“192.168.1.2”, timeout=“3”)
but it don’t go, ping go go and I don’t know how I can stop it. How to set
a timeout, so I have a string that say me (ip address is not valid or I
can’t connect to it!!).
TCP ping unsuccessful: Connection refused - "connect(2)"
UDP ping unsuccessful: Connection refused - "recvfrom(2)"
TCP adn UDP say me that are not connect but PingExternal is ok. Isn’t
strange ???
Thank you
